This invention relates to bumpers for automobiles and, in the particular embodiment disclosed herein, is especially adapted for a combined rear-bumper and corner-guard construction for use with omnibuses.

- It is the general purpose and object of the invention to provide a bumper of this character which is particularly efficient for the purpose for which it is designed. Further 10 and more limited objects of the invention are to provide a combined corner-guard and i bumper construction which is easily adaptable to bodies of varying widths; also to provide a bumper of this class by which the im# pacts will be absorbed by and dissipated throughout the bumperand corner-guard construction. 4Further and still more limited objects of the invention will be set forth hereinafter and will 'be realizedin andthrou -construction shown in the drawings, w erein Fig. 1 represents a plan view of a bumper constructed in accordance withmy invention, the cooperating parts of the vehicle being shown in dot-anddash lines and certain bolts being shown in section ';"'Fig. 2 a rear elevation of the bumper.; Figs. 3, 4, 5 and are views c'orresponding,I respectively, to the lines 33, l-4, 5-5 and 6-6 of Fig. 1. v

Describing the various parts by reference characters, 1 represents the rear 'ends ofthe side members andi. the rear cross member of a vehicle frame, 3 the rear end and 4 the rear end of the side of the body which is carried by the said frame.

The complete bumper comprises a pair of curved resilient attaching bars secured at their front or inner ends to the sides of the body, a pair of curved corner guard memv bers secured to each of the attaching bars, an impact section comprising` impact bars connected to t-he corner-guard members, and forwardly or inwardly extending cushion bars connected to the impact-.bars and to the rear or outer ends of the attaching members and interposed'between the impactv section of v the bumper and" the vehicle.

j The two attachingvbars are indicated gen- .erally at 5 and each has a front or inner end '5B which is bolted or otherwise secured to an angle iron clip 5, one flange of which is bolted beneath the bottom of the body, as indicated at 5d. The attaching members are each curved laterally outwardly and inwardly, to provide a resilient protection ymay for their respective cor-i ners of the vehicle as well as a support for the additional corner guard members. The rear 'corner guard members are curved forwardly from their respective eyes Y6` and project beyond the corresponding curved corners of the attaching bars 5, the front ends of the bars 6 crossing the adjacent portions of their corresponding bars 5 and each being provided at such front-end with an eye 6b, the aligned upper and lower eyes 6" at each end of the bumper structure being connected by'a bolt 8. Each bolt is provided with a pair of sleeves 9 thereon, eac sleeve having a seat 9 therein adapted to receivethe upper and the lower edge, respectively, of the adjacent bar 5, there being spacing washers l() interposed between each eye 61- and the sleeve 9 adjacent thereto which spacing washers are adapted to be engaged by the bars 6. By setting up the nuts 8 on the bolts 8, the eyes 6h are forced toward each other, thereby forcing the clamping sleeves 9 toward each other and firmly securing the front ends of the corner guard bars tothe attaching bars 5. j

11 denotes an upper and a lower impact bar, which bars extend across the space between `the ends of the bars 5 and 6, being secured to the latter bars by means of bolts 12.

For the purpose of securing the bumper structure to the vehicle frame, it is preferred to use a pair of cushion bars, one at each side of the central portion of the bumper structure and each 11a-ving its ends fastened to the bumper structure with a forwardly (or inwardly) bowed 15, the constructionproviding a iiattened VU- shaped projection to which an attaching arm be conveniently secured. The end porfl tion 13 of each cushionbar is secured, as by` means of a bolt 16, tothe adjacent attaching central portion which-may j provide-means for attaching supporting arms bar 5, while the inner end 14'of 'each cushion bar extends between the impact bars l1 and is secured to such impact bars by rear and front plates 17 and 18 having their ends engaging opposite faces of the bars 1.1, with bolts 19 connecting the said plates between the upper and lower edges of the ends 14 and thelower and upper edges of the bars ll-see Fig. 4.

The arms which secure the body portions of the bumper to the vehicle frame are shown as of approximately Z-form, comprising each a flattened or flanged front end 20, a rearwardly or outwardly -extendingintermediate portion 21, and a rear or outer flange 22, which is adapted to bear against the extended central portion 15 of the corresponding cushion bar. The flanges 20 are shown as secured to the rear frame member2 by means of bolts 23,

i while the flanges 22 are shown as secured to i 2do the central portions of their respective cush-A ion bars by bolts 24.

In certain installations, it may bedesirable to omit the arms 21. In this event, should the impact portion of the bumper be deflected orwardly or inwardly a sufficient.l distance, the projecting portions 15 of the cushion bars will engage the vehicle vbody orfframe and thereby exercise theirc-ushioning effect, after a blow` to the rear such deflection. Where the attaching arms 20 and 22 are employed, the cushioning effect will occur immediately upon the delivery of or impact portion ofthe bumper. v u

It will be noted that the corner-guard bars 6 and the attaching hars 5 are so constructed, arranged, and connected that they provide jointly a triple curved guard for each corner of a vehicle, while the attaching bars also constitute the means for supporting the corner- Aguard bars. AVAlso that, where the arms 21 are employed, `these arms supportethe rear or y -outer ends ofthe bars 5 and 6 from the vehicle.

When such'arms are not employed, the cu'shi ion bars serve as means for support'mgthe ends of the aforesaidbars lfrom the vehiclel by' connecting such ends'fwith the ends of tlie -opposed attaching and cornerguard bars.

1 rected toward the corner. -If the blowlis suf-v ficiently stron the impact bar will be disuo 4 voffer an additional resistance to the force of Vthe blow. The impact bars, which may be of vsas Each arm 5, vwith the attached impact bars 6, provides an inwardly concave arch extending around the 'corner of the vehicle and so presents the maximum resistancev to la blow' directed toward the corner of the vehicle from any direction. The impact bars 6 are spaced outwardly from the attaching b ar 5 andso offer the first resistance to a blow ditorted or the c amp 9 will slide upon the bar 5 so that the impact bars will come into the plane of the attachingbars andthe latter will be readily reremoving the vehicle.

a standard size and shape, may placed without the necessity of attaching members 5'fro'm` the Although the bumper has been aeseribea I and claimed as applied to the rear of a vehicle it is apparent that it may be used in other positions upon the vehicle and it is not intended to thereby limit the use of the invention to the particular position described.
